Eco-audit is a tool to find the environmental impact of the product across all life cycle stages and for identify the problems in all aspects of a supply chain, from extraction of raw materials to manufacturing, distribution, use and disposal. The purpose of an analysis of a product is to establish the embodied energy, water usage, annual CO2 to atmosphere, carbon foot print, recycle fraction in current supply, toxicity, approximate processing energy and sustainability criteria. Knowledges to guide design decisions are needed to minimize or eliminate adverse eco-impacts. In eco-audit analysis, will be created material charts, processes selection and life cycle analysis allowing alternative design choices to meet the engineering requirements and reduce the environmental impact. The application presented in this paper uses only environmentally friendly properties of Ashby's database.

Wind turbines have seen increasing use over the past decades as an alternative mode of energy production. One specific use of vertical axis wind turbines is for the powering of rural telecommunication towers. In this research a cradle-to-gate life cycle analysis is used to compare three different designs for a stackable, capped, Savonius-style vertical axis wind turbine blade capable of producing from one to three kilowatts. The analysis compares the energy consumed and carbon dioxide emissions from material production and manufacturing of two different aluminum blade designs and a polypropylene design each having the same energy generation capacity. Primary and secondary aluminum materials were included in the analysis. Life cycle inventories from two software programs were used and compared with values gleaned from published literature. The results of the analysis revealed that the least energy and carbon dioxide impact came from using a recycled aluminum design while the most was from manufacturing using primary aluminum.

Abstract Earth has lately been suffering from unforeseen catastrophic phenomena related to the consequences of the greenhouse effect. It is therefore essential not only that sustainability criteria be incorporated into the everyday lifestyle, but also that energy-saving procedures be enhanced. According to the number of wind farms installed annually, wind energy is among the most promising sustainable-energy sources. Taking into account the last statement for energy-saving methods, it is essential to value the contribution of wind energy not only in eliminating CO2 emissions when producing electricity from wind, but also in assessing the total environmental impact associated with the entire lifetime of all the processes related with this energy-production chain. In order to quantify such environmental impacts, life-cycle analysis (LCA) is performed. As a matter of fact, there are a very limited number of studies devoted to LCA of onshore wind-energy-converter supporting towers—a fact that constitutes a first-class opportunity to perform high-end research. In the present work, the life-cycle performance of two types of tall onshore wind-turbine towers has been investigated: a lattice tower and a tubular one. For comparison reasons, both tower configurations have been designed to sustain the same loads, although they have been manufactured by different production methods, different amounts of material were used and different mounting procedures have been applied; all the aforementioned items diversify in their overall life-cycle performance as well as their performance in all LCA phases examined separately. The life-cycle performance of the two different wind-turbine-tower systems is calculated with the use of efficient open LCA software and valuable conclusions have been drawn when combining structural and LCA results in terms of comparing alternative configurations of the supporting systems for wind-energy converters.

Efficient Measures

Energy conservation has become an issue of global significance, which is a focus reflected in the Australian housing industry’s renewed emphasis on energy-efficient design. The Australian Building Codes Board (ABCB) has proposed to increase the stringency of the Building Code of Australia (BCA) to ensure the industry adopts energy efficient measures, including the enhancement of thermal performance and greater recognition of thermal mass in energy rating schemes. However, this proposal’s potential to effect energy savings in tropical housing is yet to be assessed. In order to determine its relative merits under tropical conditions, a standardised house design used in the Tiwi Islands of the Northern Territory (NT) was subjected to life cycle analysis, including analysis of embodied energy, the efficiency of energy saving measures and the resulting active energy consumption. This standardised house, like others in the NT, is designed for retrofitting within 10 years, which reduces the time available for savings in operational energy to exceed energy invested in installing these measures. Housing lifespan would, therefore, significantly impact upon potential benefits resulting from changes to the BCA. In addition, the spatial distances between population settlements in the NT greatly increases embodied energy values. It was found that adopting the proposed measures would result in an increase in energy efficiency through a reduction in the need for refrigerative air conditioner use, and that the embodied energy payback period would fall within the lifespan of the house. Therefore, for this specific tropical design, the BCA’s proposed measures for saving energy were found to be beneficial.
